Solution

The correct option is B False

Noble gases have fully filled electronic configuration. They do not react with other elements to form compound nor do they react with them-self to form a molecule.

Therefore, they exist in the monoatomic state.

Bond order of $H e = \frac{B o n d i n g e l e c t r o n s - A n t i b o n d i n g e l e c t r o n s}{2}$
$= \frac{2 - 2}{2} = 0$

This shows that there is no bond between helium atom which is noble gas and it exists as monoatomic. Similar is the case with other noble gases.
